[A case of persistent proatlantal intersegmental artery with status epilepticus]

A 48-year-old woman with status epilepticus was admitted to our hospital. On admission, she was comatose with horizontal conjugate deviation of eye balls to the left side. Convulsive seizure of Jacksonian type involved initially the left mouth angle and sequentially the left arm and leg, developing into general convulsion. Routine laboratory examinations revealed no significant abnormality. CT scan was normal but carotid angiogram showed a persistent proatlantal intersegmental artery on the left side. Convulsive seizure lasted five days, followed by left hemiparesis. She recovered completely two weeks later. The origin of her illness remained unclear but the causal relationship between neurological symptoms and the persistent primitive artery was presumed.
